Galvanized containers cannot be used for storing acidic foodstuffs as zinc reacts with food acid forming poisonous compounds.

Tin coated containers and utensils can be used for storing any food stuff as tin is non-toxic and protects metal from corrosion.

Tinning is cathodic coating whereas Galvanizing is anodic coating so cathodic coating is preferred over anodic coating for manufacturing of containers to store food stuff.
